Referring in detail to the drawing, 20 denotes a liquid dispenser-container molded of thermoplastic resinous material constructed to embody the invention.

Dispenser-container 20 may be molded as desired as a thermoplastic structure having either a degree of elasticity or a relatively rigid charin which case polyethylene, cellulose acetate or similar flexible materials may be used in the manner hereinafter described.

Said dispenser-container 28 as seen from Figs. 1 to 4, comprises a body 2! which may be molded as a one-piece structure constructed to stand upright on a base 21a and terminating at an upper end with an integrally formed neck 2R), the latter being fitted with a cup shaped closure cap 22 for sealing contents C, a suitable through-opening or outlet passage 2 being provided in said neck 2 lb for emptying the contents C.

Body 2! of dispenser-container 2% may be molded by any Well understood injection process in the form shown in Figs. 2, 3 and 4 with base Zia open ended and provided with a double or skirted wall, that is, with an inner wall portion Zld spaced from a fiounced or outer wall portion Zic, said wall portions 2m and He being arched to extend as branches from which funnel tapering wall 2! extends upwardly. Outer wall portion 256 may join the body 2! anywhere along a mid-portion thereof and is here shown to make such juncture in. the lower portion spaced from and nearer to the base end of body 21. Said base wall portions 21d and Zie preferably may be of such thickness that outer wall portion 2le is relatively stilt and is formed with an ou turned rim flange 2 lg to provide a steady footing support for the dispenser-container 2G and liquid contents C, while inner wall portion Zid, which may be of tapered cross-section, that is, a wide feathered edge-margin, is of a thickness capable of being bent into shape, or flexed, to bring opposite sides of rim edge 2 In thereof together for cementing or heat sealing a bottom closure joint 2M, whereby the liquid contents C is retained in the body 2 l, as is clear from Fig. 1.

If desired to provide a finished fitted bottom for dispenser-container 2! a thin flat plate 23 corresponding in contour to the base flange 219 may be provided, said plate 23 being secured in place in any suitable manner as by cementing or heat sealing in-turned rim flange 23-0; thereof to interlock with rim flange Zlg, as shown in Fig. 1.

Dispenser-container may be made to have any desired cross-sectional shape such as polygonal, oval or circular and as clear from Figs. 1, 2, 3 and 4, when made oval in cross-section. opposite sides of the rim edge sin of inner wall portion 2101 are readily brought together for heat sealing along the long axis of the oval, and outer wall portion 2 is may be spaced a sufficient distance from the inner wall portion 21:1 to accommodate the finished heat sealed joint 2M leaving seam substantially in a straight line or bowed, if desired. However, when made circular in cross-section, heat sealed joint i227 of inner wall portion i2id, as is clear from Figs. 5 and 6, may be corrugated or crimped, that is, serpentine shaped so that same will freely fit into the circular area within flange lily of outer wall portion I 21a.

After constructing the parts as shown in the drawings and described above, the dispensercontainer 20 may be readily assembled in the following manner. Body 2| having first been molded of a suitable plastic for the service requirements, is fitted with a tight cap 22 or other stopper means, then is inverted and filled with fluid contents C through bottom of body 2| while still open. Opposite sides of rim edge 2th are next brought together and heat sealed or cemented to form joint 215i or joint IZlj. If desired closure-bottom plate 23 may be incorporated in the well understood manner to fully conceal the heat sealed joint and give a neat, finished appearance to the container 20.

The operation of the dispenser-container 20 will now be apparent. The body 2! of such dispenser-container 20 is made of flexible molded material, such as polyethylene, cellulose acetate, any other suitable thermoplastic resin, or a rubber compound, and filled with fiuid contents C, as for example a liquid or a fine powder. By first removing cap 22 and next tilting container 28 at a suitable angle for pouring out contents C through opening 2H0, a squirting action results by inwardly distorting, that is, squeezin flexible wall 2 if to dispense contents C whereby a controlled range of flow is accomplished. This effect is especially efficient when the opening 210 is of relatively small diameter.

Dispenser-container 28 may also readily be fitted with an atomizer of any well known construction. As shown in Fig. 12 an atomizer in the form of sprayer-cap 25 may comprise a tube 250; extending to the V-shaped elongated trough-like bottom of the container 20 adjacent closure joint 2! and terminating at its upper end in a nozzle 25b projecting into chamber 25d, said nozzle being spaced just short of ejector opening 25c in alignment therewith. Openings 25o are provided in chamber wall 251 to permit communication of air within container 2G with the atmosphere.

Where a spraying receptacle is desired, outlet passage 21c may be fitted with sprayer-cap 25 in the well understood manner.

The operation of such dispenser-container 20 fitted with sprayer-cap 25 for use as an atomizing receptacle will now be apparent. The contents C may be emptied or removed as desired in a fine spray by pressing, that is, grip squeezing or inwardly distorting wall 21f. In so doing, air from the space above the liquid contents C is forced out through openings 25c, chamber 25d and through ejector outlet opening 250, simultaneously the liquid contents C is forced up through tube 25a and discharged by nozzle 25b to mix with the air flow and pass out of ejector opening 250 in a fine spray or mist. Upon releasing the squeeze pressure on wall Zlf, cham ber of dispenser-container 20 assumes its original volume and atmosheric air enters through openings 25d and 259 displacing the sprayed contents. The extension of tube 25a to the V-shaped elongated trough-like bottom formed by the joint 2U enables discharge of almost the entire contents from an upright position of dispenser-container 20. Said spray container 20 will then be restored to a normal condition again ready for use. Top 7 closure cap 22 may be seated on neck 2 I b to make the container leak-proof for storage.

Fig. '7 shows a dispenser-container construction provided with a modified form of fitted flat bottom-closure 33 which may comprise a plate 33a having an upstanding circular flange 3312, the peripheral rim of which fits inside outer wall portion Me of body 2! and a clamping ring body .Md for seating body il 5 33c of L-shaped cross section secured over base flange 2 lg to plate 33a as by cemented joint 33d.

A modified form of dispenser-container 48 is shown in Fig. 8 which is similar to container 20 except that fitted flexible fiat bottom-closure plate 43 thereof is in snap-in engagement with an internal continuous groove 317c provided in in-turned rim ledge 41g formed in outer wall portion 416 in the well understood manner.

Where containers having flexible walls but relatively rigid bases or where contrasting color schemes are desired, dispenser-container 50 of modified construction embodying the invention is provided.

Dispenser-container 50 is seen in Figs. 9 and 10 to comprise a body 51 terminating in an upper integrally formed neck 5) and a bottom heat sealed closure joint 517' supported upright in a dish-shaped base 54, said body 5! being preferably of a flexible material and formed with an integral continuous outwardly extending bead ii lm to serve as a reinforced bracing spaced from said joint Sly, that is, in a mid-portion of the Base 54 may be made of a relatively rigid material such as polystyrene, nylon or other well known thermoplastic resins or of any suitable metal, and proportioned to receive the lower section tin of body 5i. Base 54 may be formed with a, side wall 54b upstanding from bottom wall -54a and a rim flange 54c shaped to seat bead Elm. Body 5! may be permanently connected to base 54 by any suitable clamp joint such as .for example annulus 55 fitted over bead 51m and cemented to rim flange 540, as clearly shown in Fig. 9, or body 5! may be removably connected to base 65 of modified form similar to base 54 but provided with a continuous internal groove on bead Elm and one or more vertical slits Me for permitting snap-in engagement between the bead Elm and groove 64d.

Dispenser-container lil, shown in Fig. 11, is a further modification of the invention which like containers 26 and 50 is seen to comprise a and heat sealed closure joint l'ly similar to bodies 2! and 5| having joints Zly', 517', respectively. As here shown body '1! may be provided with a, pair of spaced apart outwardly extending ledges Hm serving as a reinforced bracing and which form a groove H11. therebetween for receiving inwardly turned rim edge Me of base 14 in snap-in engagement. Base '14 may be of tubular shape having one or more vertical slits 14c and an out-turned bottom rim flange 14a to serve as a steadying support for the container it. Base is if desired may be fitted with a closure bottom similar to those shown in Figs. 1 and 7 or may be made dish-shaped with an integral bottom similar to base 54 of container 5%).

Dispenser-container 50 may be assembled in a similar manner to that above described for container 2% but base 54 is preferably attached after the filling and sealin operation by inserting lower section am of body 5| into base 54 so that bead 51m seats on rim flange 540 after which annulus 55 is clampingly fitted in place over bead 51m and cemented to rim flange 540 to make a permanent joint.

For utilizing base 64, snap-in assembly of the base and body is facilitated by vertical slits Me which permits spreading the rim of the base so that bead Elm may be sprung to engage internal groove Std. Likewise, rim edge 140 of base ls may be sprung for snap-in engagement in groove lln between ledges Hm.

Dispenser-containers 56 and 10 when made 6 with flexible bodies 5| and H and fitted with a sprayer-cap 25 like spray container 20, above described, will function in a similar manner.

A further modification embodying the invention may be shown in Figs. 13 to 17, inclusive, in which body 8! is molded as a one-piece structure similar to body 2| of dispenser-container 26 shown in Figs. 2 and 3 but differing in the following respects.

Body 8| which may be formed at one end with a neck 8|b is threaded, as at Blp, to engage a closure cap (not shown) of any conventional type in the well understood manner, and has a base Bla here shown as being of oval crosssection, said base am being provided with an inner wall portion Bid and an outer skirted wall portion tie which branch from an annular thickened midportion 81m. Inner wall portion 8ld may be formed as of wide feathered edge margin having a rim edge Blh which extends downwardly beyond a plane X-X and as shown in Figs. 13 and 14 is curved and of such contour that when opposite peripheral portions of said edgetlh are brought together along the long axis of the oval in said plane X-X and heat sealed to provide joint Bly', said edge am may lie substantially in a straight line, as is clear from Figs. 16 and 17.

If desired the decorative effect of the container body 8| may be enhanced and the base 81a also stiffened by providing outer wall 85s with suitable embossed means, such as scallops S, or of any other desired ornamental configuration provided, as for example, between midportion 81m and pedestal stepped element 81g, shown in Fi s. 13, 14, 15 and 16.

The body 8! may be utilized in practicing the invention in the same manner as described above for body 2i in the construction of either the dispenser-container or the atomizer 20.

It will thus be seen that there is provided improved dispenser-containers of molded plastic whereby the several object of this invention are achieved and which is well adapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention, and as various changes might be made in the embodiments above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense.
